No Internet - Crazy Malware - Excessive Processes

I'm running XP on a sony vaio laptop. I accidentally agreed to some prompt while browsing the internet and next thing I knew, popups everywhere and the screen froze. Everytime I restarted, I couldn't do anything but access taskmanager or msconfig. I had excess of 65 processes running. After starting in safemode and uninstalling a bunch of malware (still have command.exe on there that I can't delete and I know nail.exe still present) I can actually do stuff like open IE although I can't use it. At one point I found the app kill32 and ran it because I figured it couldn't get any worse and after that it stopped freezing on startup. Now there is this weird DLL error that comes on when I reboot. Anyways, is there anything specific that I should look for and can eliminate manually? I don't have any anti-virus progs or anything like adaware.
